Abstract (en)
The invention provides a system for providing improvement in cardiorenal function for a patient, the system comprising: a catheter (31, 31', 80, 90) having a proximal end (35) and a distal region (34, 72, 84), the catheter configured for intravascular placement so that the distal region is disposed in a superior vena cava (SVC) of the patient; a flow limiting element (32, 32', 50, 81, 91, 112, 130, 133, 137, 143) disposed on the distal region of the catheter, the flow limiting element configured to be selectively actuated to at least partially occlude the SVC; a controller (33) configured to be operatively coupled to the catheter to intermittently actuate the flow limiting element to at least partially occlude the SVC for an interval spanning multiple cardiac cycles; wherein the controller is configured to intermittently actuate the flow limiting element to create a negative pressure sink in a right atrium of the patient, accelerating flow from the renal vein, thereby enhancing renal decongestion and promoting blood flow across a kidney of the patient.
